10 FHD on Rock 5A - no touch

ROCK 5 Series
1

Hi, I have a Rock 5A with a Radxa 10 FHD display.

The display itself works great. I’ve enabled the overlay and graphics appear as expected.

I can’t get the touchscreen to work though. Is there anything else that needs to be enabled for this to work?

I’m running the rock-5a_bookworm_kde build b2 image.

It is possible that the wires are not connected properly, you can try to re-align and connect the wires.
can you get the msg by dmesg | grep gt9xx，and i2cdetect -y 5

Thanks for your reply. I have this in i2cdetect:

     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:                         -- -- -- -- -- -- -- --
10: -- -- -- -- UU -- -- -- -- 19 -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --

Nothing in dmesg.

I’ve reconnected the ribbon and also tried swapping with a new one, but the result is the same.

What else do you think I can try?

Send me the whole dmesg log.
sudo apt install evtest
paste the output via sudo evtest

Actually, I think you were right the first time.

I tried reconnecting again (and again, and again), and now it is working. There is some very small left/right movement on the ribbon connector at the panel end which might have been it.

Thank you,

ok, good news. Can you take a clear picture of the ribbon connector for me? I check with HW engineer.
